Description
Technical field
The present invention relates to a kind of high-barrier composite material and preparation method thereof, especially relate to a kind of ethylene-vinyl alcohol copolymer (EVOH) and polyethylene terephthalate (PET) matrix material and preparation method thereof.
Background technology
Ethylene-vinyl alcohol copolymer; Be called for short EVOH; It is a kind of novel high barrier material; Its gas barrier property is higher 10000 times than PE (Vilaterm), PP (Vestolen PP 7052), and is higher more than tens of times than barrier material PVDC (polyvinylidene dichloride) commonly used at present, is that the superlative degree that the present world finds intercepts plastics.EVOH is as wrapping material; Except gases such as oxygen, carbonic acid gas being had excellent barrier and separated flavor property; Also have performances such as superpower oil-proofness, organic solvent resistance; And since EVOH nontoxic, have no irritating odor, environmental protection, thereby can be applicable to the packing in fields such as food, medicine.But the cost value of EVOH is higher, shock resistance is relatively poor, thereby has limited its use range to a certain extent.
Through discovering; EVOH can mix with PE, PA (polymeric amide), PP, LLDPE wrapping material such as (linear low density of polyethylene); Realize having complementary advantages, form matrix material, but these matrix materials are in shock resistance with better barriering effect; On the performance of transparency and each side such as impermeable, also still owe desirable.
Summary of the invention
Technical problem to be solved by this invention is, a kind of price material benefit is provided, and shock resistance is good, and transparency is good, the better ethylene-vinyl alcohol copolymer of barriering effect (EVOH) and polyethylene terephthalate (PET) matrix material and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is:
The present invention's ethylene-vinyl alcohol copolymer and polyethylene terephthalate matrix material; It is characterized in that, constitute by the component of following parts by weight: 30～50 parts of ethylene-vinyl alcohol copolymers (EVOH), 1～5 part of silane coupling agent, 10～20 parts of anhydrous calciumsulphates (calcium sulfate crystal whiskers), 10～30 parts of maleic anhydrides, 30～50 parts of polyethylene terephthalates (PET).
Further, the matrix material of preferred version is made up of the component of following parts by weight: 40 parts of ethylene-vinyl alcohol copolymers, 10 parts of anhydrous calciumsulphates (calcium sulfate crystal whiskers), 1 part of silane coupling agent, 19 parts of maleic anhydrides, 30 parts of polyethylene terephthalates.
The preparation method of the present invention's ethylene-vinyl alcohol copolymer and polyethylene terephthalate matrix material is characterized in that, may further comprise the steps:
(1) gets the raw materials ready: take by weighing ethylene-vinyl alcohol copolymer 30～50 weight parts, silane coupling agent 1～5 weight part, anhydrous calciumsulphate 10～20 weight parts, maleic anhydride 10～30 weight parts, polyethylene terephthalate 30～50 weight parts in proportion;
(2) surface-treated of anhydrous calciumsulphate: silane coupling agent is dissolved in the mixing solutions of absolute ethyl alcohol and zero(ppm) water, wherein, the mass ratio of silane coupling agent, absolute ethyl alcohol, zero(ppm) water is 15～25:65～75:5～10; Then, the mixing solutions of said silane coupling agent evenly is sprayed on the anhydrous calciumsulphate surface, room temperature leaves standstill 1～3h, under 60～70 ℃, carries out drying again, and be 2～4h time of drying;
(3) ethylene-vinyl alcohol copolymer, polyethylene terephthalate and maleic anhydride are placed the high mixer blend, under the room temperature, blend 20～40min, and leave standstill 22h～26h;
(4) blend with dry modification anhydrous calciumsulphate of step (2) gained and step (3) gained places high mixer, under the room temperature, and blend 20～40min;
(5) step (4) gained mixture is passed through the twin screw extruder extruding pelletization, wherein, the head temperature of twin screw extruder is 140～190 ℃, and screw speed is 100～150r/min.
Further, step (3), the preferred 2h of said time of repose, preferred 60 ℃ of said drying temperature is preferably 3h time of drying.
Further, step (3), preferred 30min of said blend time.
Further, step (4), preferred 30min of said blend time.
Further, step (5), preferred 170 ℃ of said head temperature, the preferred 140r/min of screw speed.
The used anhydrous calciumsulphate of the present invention is a calcium sulfate crystal whiskers, claims crystal whisker of gypsum again, is a kind of fibrous single crystal of calcium sulfate.Because calcium sulfate is mineral filler; Ethylene-vinyl alcohol copolymer is a superpolymer, and both interface compatibilities are poor, and the present invention is through adding silane coupling agent; Owing to there is the alkyl of close superpolymer on the silane coupling agent molecular chain; The group that also has close anhydrous calciumsulphate, thereby can effectively improve the interface compatibility between polymkeric substance and the anhydrous calciumsulphate, thus improve the shock resistance of material.
Research shows that the wastewaters with modified calcium sulfate whiskers that the present invention uses has uniform cross-sectional area and complete internal structure, and this characteristic is given its intensity near valence link between crystal theoretical value-atom, and the chemical property torpescence, has chemical proofing and electrical insulating property.Because it has high intensity, trickle size is prone to polymer-bonded; Thereby can improve consistency and interface cohesive force with matrix; When receiving the foreign compulsion orientation, the unrelieved stress of polymkeric substance can pass to calcium sulfate crystal whiskers well, and then improves the shock resistance of material; Improve the water tolerance and the outward appearance whiteness of material simultaneously, and reduce cost greatly.
The used polyethylene terephthalate of the present invention has favorable shock resistance, the high-and low-temperature resistance performance; Low to gas and vapor permeability; At a distance from good, nontoxic, tasteless, the environmental protection of flavor property, mix by a certain percentage with ethylene-vinyl alcohol copolymer; Can realize having complementary advantages, and can play good synergy the barrier of gains.
The shock resistance of the present invention's ethylene-vinyl alcohol copolymer and polyethylene terephthalate matrix material is good, and transparency is good, and barriering effect is good, and nontoxic, environmental protection is specially adapted to food, pharmaceutical packings such as fresh fruit, vegetables and meat.
